Upside down with no harness
Cliff; at last you've tempted me to reply when you scanned that letter. The long arm of coincidence stretches out again.
My dad trained at 2BFTS, War Eagle Field, Lancaster, California on Stearman, Vultee Vibrator and Harvard.
One fine day, in the climb to exercise altitude in a Harvard, he decided to pass the time with a slow roll. The canopy was half open and he found himself inverted with his shoulders on its leading edge and his head in the slipstream. He couldn't reach the controls and had to kick the stick over until it rolled drunkenly upright. He had a parachute, of course, but was too scared of explaining himself (and the loss of an a/c) to the CFI to contemplate using it. I suppose the Harvard would have recovered itself over 6,000', but it made him sweat a bit.
Keep it all coming Cliff and Regle, the reason I have a PPL today is because I was brought up on little snippets, which you are bringing together beautifully.
